  I am trying to load Menu Items Dynamically in the preRender event based on user permissions.
  

  if (_UserInfo.ProvPrivInd)

  {

      RibbonBarMenuItem rbmiAddProject = new RibbonBarMenuItem();

      rbmiAddProject.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_NewEntProj_Text;

      rbmiAddProject.ImageUrl = "~/Images/Add-New-Folder.png";

      rbmiAddProject.Font.Size = FontUnit.Small;

      rbmiAddProject.Value = "NewEntProject";

      rbmiAddProject.Enabled = true;

       rbmEnterpriseActionMenu.Items.Add(rbmiAddProject);

  }

  if (!_UserInfo.ECAExecInd || _UserInfo.ECAAdminInd || _UserInfo.RRDAdminInd)

  {

      RibbonBarMenuItem rbmiAddUesr = new RibbonBarMenuItem();

      rbmiAddUesr.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_AddUsersMultiProj_Text;

      rbmiAddUesr.ImageUrl = "~/Images/Change-Group.png";

      rbmiAddUesr.Font.Size = FontUnit.Small;

      rbmiAddUesr.Value = "AddUsersMultiProj";

      rbmEnterpriseActionMenu.Items.Add(rbmiAddUesr);

      RibbonBarMenuItem rbmiRemoveUesr = new RibbonBarMenuItem();

      rbmiRemoveUesr.Text = Resources.Hub.EntMgmt_Ribbon_ActionMenu_RemUsersMultiProj_Text;

      rbmiRemoveUesr.ImageUrl = "~/Images/Delete-User.png";

      rbmiRemoveUesr.Font.Size = FontUnit.Small;

      rbmiRemoveUesr.Value = "RemUsersMultiProj";

      rbmEnterpriseActionMenu.Items.Add(rbmiRemoveUesr);

  }

  
  But when I click on the item in the browser a post back occurs but the onmenuitemclick event isn't handled.  
  I get a javascript error on the page.

  Hi Rick,
  
  When adding items to the RibbonBar, you should use the Page_Init event, since RadRibbonBar doesn't use ViewState, and any controls added after this event, are lost upon postback and cannot be recreated in time for them to work properly.
   
  All the best,
